Whole-house filters

Point-of-entry carbon and media systems treat all the water entering the home — usually for chlorine or chloramine taste and odor.

What it does

• Reduces chlorine and chloramine taste and odor at every tap and shower
• Catalytic carbon handles chloramine; standard carbon is best for chlorine — the disinfectant your utility uses decides which
• Staged versions add sediment prefiltration where particulates are measured

What it does not do

• A generic carbon bed carries no certified reduction claim for named contaminants like lead or PFAS — those need products certified for the exact contaminant, verified at the model level
• It does not soften water and does not disinfect it

Scope decides the cost

If taste at the kitchen tap is the actual concern, a point-of-use filter costs a fraction of a whole-house install and is renter-friendly. Whole-home treatment makes sense when the concern is every tap and shower — usually in an owned home.
